$\huge\mathcal\green{Question✌}$

A body weighs 700 g wt on the surface of the earth. How much will it weigh on the surface of a planet whose mass is 1/7 and radius is half that of the earth

$\huge\colorbox{blue}{answer ☺❤}$

g=GM/r^2

m1=700g

M^1=M/7&R^1=R/7

W1=m^1Gm^1

R^1^2

W1=400gm−wt

Answer 2

$\mathbb{ \red{REQUIRED }\: \blue{SOLUTION }} \ddot{ \smile}$

$\bf{}g = \dfrac{GM}{ {r}^{2} }$

$\bf {m}^{1} = 700g$

$\bf{} {M}^{1} = \dfrac{M}{7}$

$\bf{} {R}^{1} = \dfrac{R {}^{1} }{7}$

$\bf{} {W}^{1} = \dfrac{{m}^{1} {GM}^{1} }{R {}^{1 {}^{2} } }$

$\underline {\boxed {\bf{} {W}^{1} = 400gm - wt}}$

$\text{so done!\checkmark}$
